NBC News said Friday that they have fired the producer who edited George Zimmerman's 911call from the night he shot 17-year-old Trayvon Martin. The network had already acknowledged that the tape was misleadingly edited. In the aired version Zimmerman said, "This guy looks like he's up to no good. He looks black." But in the original recording those two sentences are separated, with Zimmerman classifying Martin as black only after asked about the teen's race. NBC says the editing was an accident.
